Question

A container has a total capacity of 25 qt.
If $\frac{2}{4}$ gal of water is already filled in it, how much more water is required to fill the container completely?

Answer 1

$\text{Capacity of the container}$ $\text{= 25 qt}$

$\text{Amount of water available in it}$ $\text{=}\frac{2}{4}\text{gal}$

$\text{Let's convert}$ $\text{gal to qt.}$

$\text{We know that,}$
$\text{1 gal =}$ $\text{4 qt}$


So,
$⟹\frac{2}{4}\text{gal =}$ $\frac{2}{4}$ $\times$ $\text{4 qt}$ $=2\text{qt}$

$\text{Hence, out of 25 qt capacity}$ $\text{of the container, 2 qt is already filled.}$

$\therefore \text{Amount of water to be filled}$ $\text{= Total capacity – Amount of water available}$
$=\text{25 qt – 2 qt}=\text{23 qt}$

$\text{Therefore, 23 qt of water is required}$ $\text{to be filled in the container.}$
